Description dje 2010-10-13 17:20:33 UTC 
Given this testcase:

typedef int my_int;
typedef const my_int const_my_int;
typedef volatile my_int volatile_my_int;
typedef volatile const_my_int volatile_const_my_int;
typedef const volatile_my_int const_volatile_my_int;

my_int v_my_int (0);
const_my_int v_const_my_int (1);
volatile_my_int v_volatile_my_int (2);
const_volatile_my_int v_const_volatile_my_int (3);
volatile_const_my_int v_volatile_const_my_int (4);

int
main ()
{
  return 0;
}

ptype will drop const/volatile information.

(gdb) ptype v_const_my_int
type = int
(gdb) ptype v_volatile_my_int
type = int
(gdb) ptype v_const_volatile_my_int
type = int
Comment 1 Tom Tromey 2013-02-06 14:46:38 UTC 
These all work for me with CVS HEAD:

(gdb) ptype v_const_my_int
type = const int
(gdb) ptype v_volatile_my_int
type = volatile int
(gdb) ptype v_const_volatile_my_int
type = const volatile int
(gdb) ptype v_volatile_const_my_int
type = const volatile int


I'm using the Fedora 16 system gcc.
If it still fails for you I would suspect a compiler bug.

I'm closing the bug.
